Publication: The ASPECTA toolkit: affordable full coverage displays

Full Coverage Displays (FCDs) cover the interior surface of
an entire room with pixels. FCDs make possible many new
kinds of immersive display experiences - but current technology
for building FCDs is expensive and complex, and software
support for developing full-coverage applications is limited.
To address these problems, we introduce ASPECTA,
a hardware configuration and software toolkit that provide
a low-cost and easy-to-use solution for creating full coverage
systems. We outline ASPECTA's (minimal) hardware requirements
and describe the toolkit's architecture, development
API, server implementation, and configuration tool; we
also provide a full example of how the toolkit can be used.
We performed two evaluations of the toolkit: a case study
of a research system built with ASPECTA, and a laboratory
study that tested the effectiveness of the API. Our evaluations,
as well as multiple examples of ASPECTA in use, show how
ASPECTA can simplify configuration and development while
still dramatically reducing the cost for creators of applications
that take advantage of full-coverage displays.
